hi chocolatechef -
First - I have no experience with electric grain mills (tho I do use the KA grain mill attachment), however...
about 6 months ago when I did some serious 'net research on this very topic, I ended up liking the Grain Master Whisper Mill the best and after that the Nutrimill - both are electric and get good evaluations - the Whisper Mill is significantly more affordable but the Nutrimill has more flexibility and higher capacity (if money is no object :? )
I unfortunately deleted all the URL-s when I decided that something like this was definitely out of my price range, but here's a quick comparison chart to get you started http://www.nutritionlifestyles.com/g...comparison.htm
If you do purchase, let us know what you chose and your feelings about it - I, for one, would be very interested.
Best of luck
